 A new Isis video shows children leading Syrian captives to their execution, distributing knives for their beheading, and then witnessing the gory event. 

Eight Syrians, said to be Shia Muslims, were beheaded by Isis as per the latest sickening video released by the group online on Sunday. 

While this is not the first beheading video coming out of the Islamic State, in this one, teenaged boys are seen leading the captives to a field for their execution.

The children, who are seen smiling, then hand over knives to the adult jihadists who go on to behead the men, calling them "impure infidels." 

The video comes weeks after Isis released a video showing a child soldier shoot dead an 'Israeli spy'. 

The videos reveal the group's intention to recruit young members into their fold, calling them 'Cubs of the Caliphate'. 

According to the Syrian Observatory for Human Rights, the Islamic State has recruited 400 children since the beginning of this year.

"They use children because it is easy to brainwash them. They can build these children into what they want, they stop them from going to school and send them to IS schools instead," Rami Abdulrahman, head of the British-based Observatory, told Reuters.
